The Analog-Frontend (AFE) IP consists of programmable current and voltage preamplifier followed by a Successive Approximation Register (SAR) architecture ADC using charge-redistribution technique. The ADC IP is configurable regarding resolution (6-13 bit) and sample rate (up to 10kS/s). The preamplifier offers programmable gain from 0.5 to 4. The input voltage range is quasi-rail-to-rail guaranteeing more than +- 1.7 V @ 1.8 V power supply. An optional calibration technique can be applied to compensate degraded mismatch behavior of t echnology capacitors. The overall power consumption of the AFE IP sums up with 10.5 μW at 1 kHz input signal.
